Such pickups are apparently popular with metal guitarists, since they allow you to drive the front end of your guitar amp harder and produce more preamp distortion.

I just scoped my Stratocaster... for normal playing it's goes up to 500mVp-p and maybe just a little bit more.  Fingerpicking can double that.

Most guitar amps have the input directly driving the grid of a 12AX7 stage, and if you check out the curves, you'll see that it's limited to under about 4 volts p-p.  So that's a serious practical limit.
